For example, a very useful service is the "Root Actions Servicemenu", which allows many functions to be performed with root (superuser or "sudo") permissions. This is necessary, for example, for editing text files that have root permissions.

The "Scan with ClamAV" service allows the anti-virus scanner to be run from Dolphin.

Once the new services have been installed, the system must be rebooted for the newly added service menus to appear in Dolphin.

<Right-click> on an item within Dolphin to bring up the services menu. For example, once the Root Actions Servicemenu has been installed, I can edit a text file with root permissions by <right-clicking> on it and selecting

Root Actions -> Open as text

This will open the text editor (kate) as root.

Other popular service menus include audiokonvertor, Extract and Compress, servicemenu-pdf, image2pdf, and vlcappend.

FFMpegThumbs uses FFMPEG to create thumbnail frames from video files, which can be used by KDE from a file manager like Dolphin. Install:

sudo apt-get install ffmpegthumbs

Alternatively, install kFFMpegThumbnailer (sudo apt-get install kffmpegthumbnailer), which works in a similar manner. (Both require FFMPEG to be installed.)

After installation of either of these modules, log out and log back into (or restart) your system for changes to take effect.

MPlayerThumbs not only shows a video frame thumbnail in Dolphin, it also has the capacity to show the entire video in the Dolphin Information side panel (for previewing). Though more powerful, it is slower to load than either FFMpegThumbs or kFFMpegThumbnailer. (MPlayer must also be installed for this thumbnailer / previewer to function.) Install:

sudo apt-get install mplayerthumbs

After installation, log out and log back into (or restart) your system for changes to take effect.

After installation, the device should appear in the Dolphin (or Konqueror or Rekong) file manager when the USB cable is plugged in.

Troubleshooting Android device connectivity: As a security precaution the newest Android devices do not have USB transfer capabilities turned on by default. It is necessary to carefully consult your device's user manual to find the method for enabling USB transfers (also known as "USB debugging mode" on many devices). For example, on my device, it was necessary to tap the "Settings -> About phone -> Build #" button 7 times to merely enable the USB debugging option, and then enable "Settings -> Developer options -> USB debugging" as a separate step!

Of course, if you are using a proxy, make sure that the proxy settings are correctly specified and that the proxy is working. When Konqueror (or Rekonq) connects successfully to the Internet, so should Dolphin.

Plasma Media Center

Konqueror

Konqueror is a KDE-integrated web browser that can also be used as a file manager. In addition to having tabbed browsing capabilities, it can transparently access FTP and SFTP servers, zip files (and other archives), and smb (Windows) shares, and can even browse and rip audio CDs. It is extensible and customizable through a system of plugins.
